pop up problem

i have a 4" pop up hunter head it seem and it started not to long ago
that every time it ups up i found the spray in a different position. i manual adjusted with no success.i replace the inside of the head and left the body there.problem still persist.any idea or help will be appriciated thanks in advance. []

ok i finally inspect those pop up and they look ok. i replace the inside of the heads with new popup and spring just in case. i have 5 hunter head with rainbird spray on these zone and two of them everytime a new cycle starts the spray is pointing not in the direction a place them. any help please i'm going insane i can't believe that is happing only on those two heads in all of my 5 zones.

hunter adjustable sprays will sometimes open up more or close if the pressure is high. never use an adjustable hunter spray as a full circle as they tend to "close" under high pressure. they supposedly fixed this problem but i dont believe it as i have had problems from customers who have these heads still to this date.

ok thanks to all. last night i rechecked and notice the inside of the body the groves(tabs) were worn out at the top of the head body unit. i'm sorry i did not understand earlier reply from gregory1420. it would have save me a few days.part of learning thanks again to all

one more thought.
yes i do use srs hunter spray, sois either the Hunter Pro Spray or a Rain*Bird 1800 Series spray body same as hunter srs. because i have a good # of the guts the pop up and spring and all of the srs stuff.would i be able to use those in the new spray as a spare part

No. they are not the same. Close, but not close enough.... I would suggest changing them out to either a Hunter Pro Spray or a Rain-Bird 1800 series Spray. The SRS Series was notorious for this very problem. You want to look for a spray body that offers a slip / click adjustment clutch. It will be the extra plastic piece at the bottom of the spring on the riser / piston body.
